IMPROVEM ENT IN HOUSE-VENTILATION.

Specification forming part of Letters Patent No. 223,006, dated December30, 1879; application filed November 17, 1879.

,To all whom it may concern:

Be it known that we, THos. B. PIERSON and OSWALD J. BURNETT, ofMorristown, in the county of Morris and State of New Jersey, haveinvented certain new and useful Improvementsin House-Ventilators; and wedo hereby declare the following to be a full, clear, and exactdescription ofthe invention, such as will enable others skilled in theart to which it pertains to make and use it, reference being had to theaccompanying drawings, which form part of this specification.

described hereinafter.

Figure 1 is a vertical cross-section of a house to which our system ofventilation is applied; and Fig. 2 is a horizontal section of the same,taken through the second story.

a represents a public or private building of any desired construction,all of the rooms of which have a fresh-air pipe, 0, leading into themthrough the side of the house at any suitable distance above the floorsd. The upper ends of these pipes reach up to very near the ceiling, soas to discharge the fresh air into the top of the room, and the upperends are covered with a wiregauze, so as to break the currents of airand prevent a draft through the room. In the pipes c are placed valves,near their lower ends, so that the amount of air admitted into the roomcan be controlled at will.

Leading from the floor of. each room is a foul-air pipe, 0, which hasits lower end connected either with the shaft 9 or an outer jacket, h,surrounding the furnace t. This furnace may be placed in the cellar orlower part of the house, and be of any desired construction, andinclosed in the usual jacket 1. Fresh air is supplied to this furnace,through the pipe at, from the outside of the building, and after the airis heated it is supplied to the different rooms through the hot-airpipes 0.

The products of combustion from the furnace pass oif through thesmoke-pipe Y, which extends up through the center of the shaft, so as toheat the air in the shaft and cause an upward current. Any other meansfor heating the air in the shaft may be resorted to, as the object is tocause an upward draft, and thereby form a partial vacuum in the lowerpart of the shaft, so as to suck the foul air from the foul-air pipes.Ward draft is caused in the shaft the foul air will be sucked into it,and thus the foul air will be carried off from the rooms as soon as itfalls to the floor.

The air in the outer jacket, h, becomes heated by contact with the innerjacket, 1', and thus an upward draft is started through it toward theshaft, and this draft causes suction enough to draw the foul air fromthe rooms above. Thus, while the furnace draws the foul air from therooms above on one side, the shaft draws it down from the rooms on theother side of the house.

Having thus described our invention, we claim- 1. The combination of thefresh-air pipes c, foul-air pipes a, shaft g, and a means for heatingthe air in the shaft, so as to cause a partial vacuum therein,substantially as described.

2. The combination of the furnace i, and its two inclosin g jackets h l,with the foul-air pipes, shaft g, and smoke-pipe passing up through theshaft, substantially as shown.

In testimony that we claim the foregoing we have hereunto set our handsand seals this 11th day of November, 1879.
